Sounds like a lot for a simple, Misfit-esque looking wearable. If that's not convincing enough, the Switzerland/San Francisco startup is submitting a research paper on its findings to be peer-reviewed by a reproductive journal.

According to the Ava site, the team is also planning to push out more clinical studies to hone its algorithms "for use in both pregnancy recognition, pregnancy monitoring, and possible use as a non-hormonal contraceptive device."

With the wearable, the company hopes women can better track their bodies to figure out the best time to conceive. That's apparent in the research and the fact that Ava is FDA approved, classified as a medical device rather than a sleep tracker or step counter.

So me and my partner have been trying for a baby for the last 6 years now and we have had no luck. I don’t have a regular cycle so it is hard for me to tell when I’m ovulating or not, but we always have sex at least 2 times a week, sometimes more. I know it can take up to a year to conceive but everyone i know who have had a baby have conceived within 2-3months of trying and it is really getting to me. my partner had a fertility test about a year ago and his sperm were fine. I’m thinking it could be a problem with me but I’ve never had any symptoms of any problems. My partner does smoke and have the occasional drink, and i used to smoke and also have the occasional drink. i know i’m slightly overweight but that shouldn’t affect our chances too much,one faithful day my friend told me to contact a spiritual coven that help her sister, then i sent them an email which was giving to me ,[email protected] . after three months the doctor confirm that i am pregnant.
